In AZ a popular thing to do is to fill old microwaves with Tannerite. You place a couple of them in along a length of desert wash and get all geared up with your combat & camo gear. Then you go maneuver up to them as quick as you can in a group and shoot them up till they explode. Guy who makes the most blow up wins.
You get to realize how heavy all that stuff is and how geeked up you get when gunfire and explosions happen around you. Everybody is sucking wind and looking rattled when your done.
Bring earplugs.
BTW, a .22 cal. won't make it explode but an M-4, AK or AR ammo does make it go boom.
